Unfortunately, Gudebrod is OUT of the fly tying business. The PRESENT Orvis fly tying thread is Gudebrod and you may be able to find some Gudebrod branded stock at certain fly shops.

It is GREAT stuff and all that I use with the exception of Pearsall's. When you look at the various charts and IGNORE the inaccurate and misleading "aught" system and seek out denier comparisons; Gudebrod is consistently one of the strongest threads when compared to other brands of the same DENIER.
